Greater Blowgun

Like its smaller cousin, the greater blowgun is often used to deliver poison. The darts it fires are larger than blowgun needles, but smaller than a thrown dart. These darts deal damage in addition to delivering poison. A greater blowgun requires two hands to use or reload. Loading a blowgun is a move action that provokes attacks of opportunity.
A greater blowgun has a maximum range of five range increments.
